Engineered and ergonomically contoured to ensure warmth, comfort, and ease of use in any position.

Constructed with features you expect from a traditional mummy bag with additional body mapped insulation to optimize warmth where you need it and minimize pressure points and other ‘side effects’. The Sidewinder SL is a side sleeper’s dream bag with technical features that roll seamlessly from one adventure to the next, and from one side to the other at night.
